The Mataranka Lateral is a lateral transmission pipeline in the central region of the Northern Territory. The pipeline is owned and operated by APT Pipelines, a subsidiary of the APA Group.

The Mataranka Lateral is 11 km in length. The Mataranka Lateral connects customers in the Mataranka region to the Amadeus Gas Pipeline. 

The Mataranka Lateral is currently a non-scheme pipeline, and is subject to the access regime for non-scheme pipelines under Part 10 of the National Gas Rules (NGR). It was previously subject to the access regime for non-scheme pipelines under the former Part 23 of the NGR, which was replaced by Part 10.

The AER has granted the following exemptions for the Mataranka Lateral:

• On 13 December 2017, a five year Category 2 exemption under Part 23 of the NGR.
• On 30 November 2022, a five year Category 2 exemption under Part 23 of the NGR. Due to reforms to the NGR, the exemption transitioned to a Category 2 exemption under Part 10 of the NGR.

The Mataranka Lateral was completed in 1997. It was previously owned by the Amadeus Gas Trust, which was owned by AGL (96 per cent interest), the Northern Territory Government (2.5 per cent interest) and a corporation representing certain Aboriginal interests (1.5 per cent).
